Melted Glow Plug Tips
These glow plugs from a 6.0L Power Stroke diesel engine tell a grim story. Removed to perform a manual compression test they are the result of a failed turbocharger that leaked a lot of oil into the charge air cooler. The oil is drawn onto the engine where it causes pistons and glow plugs to melt. The engine these came from actually "ran way" resulting in no compression in three cylinders.
